Shopmaster has posted his thoughts on Dynamic Player Performance over at MyMaddenPad, and how it affects gameplay in Madden NFL 12.
"When Phil Frazier sat down with us at the beginning of that first day he talked a little bit about Dynamic Player Performance and how players would change during the course of the game depending on how the game and that player progressed throughout. He showed a picture of Adrian Peterson running the ball and said this is what Peterson looked like running the ball in the first quarter. The picture showed Peterson with ball loosely at his side like a loaf of bread. He then showed us a picture of Peterson after he had a fumble and this pictured showed him securing the ball while he was running. Phil also stated that not only will he carry the ball more securely but he doesn’t try to break out of tackles after some fumbles. So what does this mean, it means that EA has added to the realism of the game."
